* ARM Global Timer Cortex-A9 are often associated with a per-core Global timer.** Timer node required properties:- compatible : Should be "arm,cortex-a9-global-timer" Driver supports versions r2p0 and above.- interrupts : One interrupt to each core- reg : Specify the base address and the size of the GT timer register window.- clocks : Should be phandle to a clock.Example: timer@2c000600 { compatible = "arm,cortex-a9-global-timer"; reg = <0x2c000600 0x20>; interrupts = <1 13 0xf01>; clocks = <&arm_periph_clk>; };
